ENV 3001 – Global Learning (GL) Assignment
This assignment provides a brief background on materials use and waste management.
Topic 2: Persistent waste materials (plastics) in the environment
discuss the issue and develop an overview of the problem as described in the Topic below. Your report should address the points as indicated, estimated of quantities, materials and other relevant information.
Please limit your report to about 4-6 pages (appendices are OK) including figures, tables, calculations, references.
Topic 2: Persistent waste materials (plastics) in the environment
Decomposition characteristics of plastics in the environment depends on both the conditions in the environment and the characteristics of the polymeric material. Degradation rates of the plastics (even those with added starch) depends strongly on the type and amount of additives used. The half-life of most plastics is over 100 years in landfills or the environment.
Select one type of plastic (PP: polypropylene, PS: polystyrene, PET: polyethylene terephthalate, LDPE: low density polyethylene, HDPE: high density polyethylene PVC: polyvinyl chloride) and discuss:
where it is used
how much is used and discarded
provide preliminary calculations for use and discarding rates of the specific type of plastic
